One Pot Creamy Pesto Pasta in 20 Minutes

Hear that hiss? That's the sound of chicken breast hitting a hot skillet, and it's the best part of my Tuesday nights. I used to be the person who had a pot for pasta, a pan for meat, and a bowl for the sauce, only to end up with a mountain of dishes that made me hate the meal I just cooked.

I stopped doing that three years ago. I realized that if you cook the pasta right in the broth and cream, you get a sauce that clings to every noodle without needing a fancy reduction. This One Pot Creamy Pesto Pasta is my go to when I have exactly 20 minutes before the kids start asking "is it done ?"

You can expect a meal that tastes like you spent an hour in the kitchen, but you'll actually be leaning against the counter watching the pasta bubble. It's hearty, comforting, and doesn't leave you with a sink full of grime.

One Pot Creamy Pesto Pasta

Starch Retention

Cooking the pasta in the liquid keeps the starches in the pan, which acts as a natural thickener for the sauce.

Fat Balance

The combination of heavy cream and olive oil prevents the pesto from breaking, keeping the sauce smooth.

One Pan Searing

Searing the chicken first creates a brown crust that adds a deeper flavor to the broth.

What the Ingredients Do

Quick Cooking Details

- Pasta

12 oz (340g) penne or fusilli

- Liquid

2 cups (480ml) chicken broth + 1 cup (240ml) heavy cream

- Protein

1 lb (450g) chicken breast, bite sized

- Flavor

1/2 cup (125g) basil pesto, 1/2 cup (50g) Parmesan, 1 tbsp lemon juice

- Aromatics

2 tbsp olive oil, 3 minced garlic cloves, 1/2 tsp salt, 1/4 tsp black pepper

Chef's Note: Freeze your butter or cream for 10 minutes before adding if you want a slightly thicker bind, though it's not mandatory for this recipe.

The Only Tools Needed

You only need a 12 inch deep skillet or a wide Dutch oven. A wide pan is better because it lets the liquid evaporate evenly. If you use a narrow pot, the pasta on the bottom might overcook before the top is done. Use a silicone spatula or wooden spoon to stir, as these won't scratch your pan.

Step by step Method

Searing the Chicken

Heat 2 tbsp olive oil in your pan over medium heat. Add the chicken pieces and cook 5-7 mins until they are golden brown on all sides. Toss in the minced garlic and sauté for 60 seconds until you can smell it throughout the kitchen.

The Simmer Stage

Stir in the dry pasta, 2 cups chicken broth, 1 cup heavy cream, salt, and pepper. Bring the liquid to a gentle boil. Once it bubbles, turn the heat down to low medium. Simmer uncovered for 10-12 minutes, stirring often so the pasta doesn't stick to the bottom.

The Glossy Finish

Remove the pan from the heat immediately once the pasta is al dente. Stir in the basil pesto, Parmesan cheese, and lemon juice. Fold these in gently until the sauce looks silky and uniforms. The residual heat will melt the cheese without cooking out the fresh basil flavor.

Fixing Common Issues

If your sauce feels a bit off, it's usually a heat or liquid issue. Too much heat can cause the cream to split, while too little liquid leaves the pasta hard.

Sauce Too Thin

This happens if the broth didn't reduce enough or you used too much liquid. Let the pan sit off the heat for 5 minutes, as the pasta will continue to absorb moisture. If it's still runny, stir in an extra tablespoon of Parmesan.

Pasta Still Hard

You might have had the heat too low or the pan was too crowded. Add 1/4 cup of warm broth and simmer for another 2-3 minutes.

Pesto Lost Color

Basil turns brown if it boils. This is why we add the pesto at the very end. If you cook it, the flavor becomes dull.

Adjusting Your Portion Size

When you need to feed a crowd or just yourself, don't just double everything blindly.

Cutting it in half: Use a smaller 8 inch skillet. Reduce the simmer time by about 20% since the liquid will reach a boil faster.

Doubling the recipe: Use a very large Dutch oven. Only increase the salt and pepper to 1.5x instead of 2x, as the broth's sodium concentrates as it reduces. Reduce the total liquid by about 10% (use 3.5 cups broth instead of 4) to prevent the sauce from becoming too soupy.

Pasta Logic Myths

Some people think you need to salt the water heavily for one pot meals. In this Easy One Pot Pesto Pasta, the chicken broth already provides a significant amount of sodium. If you over salt the start, the final reduced sauce will be too salty to eat.

Another myth is that you should boil the pesto. According to Serious Eats, high heat destroys the volatile oils in basil. Always stir in your pesto at the end to keep that bright, punchy taste.

Storage and Leftovers

Keep leftovers in an airtight container in the fridge for up to 4 days. The pasta will absorb more sauce as it sits, so it will be thicker when you eat it the next day.

To reheat, add a splash of water or milk to the bowl before microwaving. This loosens the sauce back up. I don't recommend freezing this dish because the heavy cream can separate, leaving you with a grainy texture.

For zero waste, save your Parmesan rind. Toss it into your next pot of soup or stock to add a deep, salty richness. If you have leftover pesto, freeze it in ice cube trays for a quick flavor boost in future meals.

The Best Sides

Since this is a rich dish, you need something acidic or crisp to balance it. A simple arugula salad with a lemon vinaigrette works wonders. If you want something heartier, a side of roasted asparagus or sautéed zucchini provides a nice snap.

For a full meal, serve this with a piece of toasted ciabatta rubbed with a raw garlic clove. The crunch of the bread against the creamy pasta is a great contrast.

Other Tasty Twists

If you want to change things up, try adding 1/2 cup of halved cherry tomatoes during the last 3 minutes of simmering. They burst and add a sweet acidity that cuts through the cream.

For a One Pot Pesto Pasta Vegetarian version, swap the chicken for chickpeas or sautéed mushrooms. Use vegetable broth instead of chicken broth. If you prefer something a bit more traditional, you can check out my traditional pesto pasta for a lighter approach.

If you're craving something even more decadent, try adding a handful of spinach at the very end. The heat from the pasta will wilt the leaves in seconds. For those who love a bit of a kick, a pinch of red pepper flakes added with the garlic makes this One Pot Creamy Pesto Pasta feel much more spirited. You could even try a homemade basil pesto pasta if you have a bunch of fresh basil in the garden.
